The specific embodiment
Fig. 1 is the decomposition diagram that pump in accordance with the present invention is sent first embodiment of device, and this device comprises pumping part, and this pumping part comprises the ozzle 1 with Venturi-tube action.Ozzle 1 links to each other with the packing 5 of closed capsule (capsule, little bowl, cuvette) shape, seals this capsule with deformable capping 7, and this can see in Fig. 2.Packing 5 comprise one the end of from 11 cavities 9 to capping 7, this capping has the opening concentric openings 8 with cavity 9, its size is equal to or less than the opening of cavity 9 substantially.Typically, thermoforming that can be by plastics or injection and obtain described capsule with single member.In an example shown, the overall shape of described packing is an annular.
Cavity 9 is 11 side joints receipts ozzle 1 end of at, and receives connector 13 at capping 7 side joints, and this connector is mounted to the bottom 14 of ozzle 1 to form fixing and opening device.In this first embodiment, by tightening connector 13 is fixed on the ozzle 1, but also can be fixed, for example clamping (clipsage) with other any method.In Fig. 2, also be shown in broken lines the clamping ring 15 of the capping 7 between ozzle 1 and connector 13, and in the closed-loop 17 of the bottom of cavity 9, these will be described in detail in conjunction with Figure 10-13 later.
Referring now to Fig. 3 and 4,, can see that it is columniform main body 4 that ozzle 1 has overall except that fin 19, the back that acts on of fin is introduced.The top of ozzle 1 comprises that steam enters well chamber (chamber) 21, and this well chamber is used to hold the socket pipe 22 (Fig. 9,10 and 11 in can see) of adapter 23, and this socket pipe is positioned at the pipe of steam generator, for example on the pipe of espresso coffee machine.In an example shown, adapter 23 is " bayonet socket " formulas, and it cooperates with two recesses 10 and two grooves 12 of the diametrically contraposition that is formed on ozzle 1 top.Therefore fin 19 can prevent ozzle to rotate with respect to described capsule.
Arrange steam to enter well chamber 21 in the main body of ozzle and can prevent that the liquid that is pumped from rising again, this rises again may be because the vortex in the suction chamber 25 causes, and has therefore kept steam to enter the contact of Guan Buyu liquid and this is always very effective.
Especially referring to Fig. 4, can see that steam enters well chamber 21 and is communicated with suction chamber 25 by means of very little restriction portion (reducing) 27 of diameter now, this restriction portion can make the delivery fluid with the velocity of sound or pass through near the speed of the velocity of sound at least.This restriction portion 27 has reduced the cross section, this thereby can in suction chamber 25, produce and realize the necessary pressure drop of Venturi-tube action.Equally, steam enters well chamber 21 and restriction portion 27 can be formed in the member of the remainder that is independent of described ozzle, perhaps utilizes this steam to enter pipe when pipe is bonded in this ozzle to be formed when steam is entered.
Diameter is positioned at the downstream of suction chamber 25 greater than the restriction (contraction flow region) 26 of restriction portion 27, and this restriction can be regulated the flow that the liquid that is sucked passes through according to speed.Suction chamber 25 is communicated with combined shaft chamber 29 by means of restriction 26 itself.The introducing passage or the pumping passage 33 of liquid also lead in this suction chamber 25 in air induction passage 31 and the packing.
Just as known, final foam quality depends on several factors, and is main relevant with air mass flow, and air mass flow can be controlled by very accurately calibrating air induction passage 31.Should be understood that, the diameter of this air induction passage is the order of magnitude of a few tenths of millimeter, therefore this calibration is accurate relatively, this is special because this ozzle is for example to produce in batches by the injection-mold pressing of plastics, and described plastics for example are polypropylene (PP), polystyrene or other suitable plastic.Here it is provides diameter bigger mouth 32 reason at air inlet, and this mouthful can assemble the device that can control air mass flow better.For example assemble permeable membrane, for example be fixed on the permeable membrane 32a on the mouth 32 with controlled porosity.For example be Pebax  or be to obtain this film in the product line of Gor-tex  by the trade mark that Gor company (U.S.) provides at the trade mark that Atofina (Paris) provides.Under the situation that does not change the ozzle main body, this film 32a also can select to be more suitable for the porosity of given steam generator pressure.Also observe, do not use described ozzle under the situation of emulsion, then the maximum gauge of described mouthful 32 of shutoff easily if be not used for producing only being used for heating liquid.
In Fig. 5, also see, liquid is introduced passage 33 and is formed in main body 4 inside of ozzle 1, in an example shown, inlet 34a, 34b, 34c is positioned at the bottom 14 of ozzle 1 in the example shown, and when this device was the pumping configuration, described inlet was used for being communicated with the package interior that contains liquid.
When providing ozzle to be used for to connect the packing of sealing (seeing Fig. 1 and 2), the vertical external of ozzle 1 also comprises groove 35, this groove can be when the liquid in the pumping packing pressure of the described capsule of balance.It is to be communicated with the package interior that contains liquid in pumping when configuration that the bottom 36 of this groove 35 is arranged in described device.
Can also see that the end of combined shaft chamber 29 comprises the internal thread 30 that is used for fixing connector 13, therefore describe the embodiment of this connector below with reference to Fig. 6-8.
Connector 13 comprises main body 40, and the bottom of main body comprises flange 42, comprises vault 44 at its other end.Vault 44 links to each other with main body 40 by contraction flow region 46.Be heated and/or the injection catheter 48 of emulsified liquid passes main body 40 (see figure 8)s below contraction flow region 46.Main body 40 comprises external screw thread 41 near its bottom, it can tighten to connector 13 on the respective threaded 30 of ozzle 1.For this tightening become easily, flange 42 comprises two handle holes 43, can certainly imagine other device for screwing up, comprising installing by damage type (anti-damage type).In fact, for the purpose of health, wish that also ozzle 1 can not be removed and reuse after first the use.In addition, can obtain this infrangibility by adopting other device that can be for example assembles ozzle 1 and connector 13 by clamping.Also observe at last, the base diameter of vault 44 is more a little bit smaller a little than the internal diameter of combined shaft chamber 29, so that force emulsion to pass through between the bottom of the wall of combined shaft chamber 29 and vault 44, thereby improves its foaming behaviour, preparation is homogenized, and limit the danger that spills.
Referring now to Figure 10-13,, these accompanying drawings are along the X-X line of Fig. 9 and the partial sectional view of XI-XI line, to describe the ozzle 1 according to first embodiment as described above below and be coupled to capsule 5 and effect during by capping 7 sealings, this situation is for example shown in Fig. 1 and 2.Can observe in these figure, capsule 5 comprises the rib of some, and some rib 6a are mainly used to reinforce capsule 5, and other ribs 6b is used for guiding the fin 19 of ozzle 1.
Figure 10 shows the ozzle-capsule system before opening, and that is to say that the inclusion of capsule 5 is not communicated with liquid introducing passage 39.In the figure, ozzle-capsule system comprises adapter 23, and this adapter comprises the bayonet socket device, and this bayonet socket device can enter well chamber 21 with the steam that socket pipe 22 is connected in the ozzle 1 by opening 24.
The ring 15 of capping 7 is clipped between ozzle 1 and the connector 13 hermetically, bonds hermetically or seals the end of cavity 9 by the retainer ring 17 around ring 15 capping 7.
Also it is contemplated that with the ring 15 sealing to the bottom 14 of ozzle 1 or sealing to the flange 42 of connector 13.In this position, the liquid and the external world isolate fully, supply opening 34a, and 34b, 34c (Fig. 5) and the air supply opening 36 that is used for equalizing pressure all are in the top of ring 17, are bonded to capping 7 hermetically and encircle 17.In preferred embodiment shown in Figure 10, can see that the length of cavity 9 wants to make capping 7 to be convex shaped before unlatching.
Shown in the arrow F of Figure 12, when capsule 5 moves with respect to ozzle 1 vertically, ring 17 is broken away from.Therefore capping 7 is depression shape.Make feed flow hole 34a (can't see 34b and 34c in the section) and the fluid connection that is contained in the capsule thus on the one hand, the bottom 36 of groove 35 is communicated with outside air A, thus the pressure in the balance capsule 5.As seeing among Figure 13, when the enable possition, contact with the lower limb 9a of cavity 9 by making the convex shoulder 20 that is positioned at described ozzle bottom, can limit the stroke of ozzle 1, this has been avoided too acutely tearing capping 7 owing to moving.In this structure, because suction chamber 25 and pack between the liquid surface in 5 and have pressure reduction, therefore the liquid that is contained in the packing 5 cannot be introduced free flow in the passage 33 at liquid, wherein packs the pressure pressure in the packing 5 when opening naturally in 5.Therefore liquid can not pass the outside that passage 33 freely flows to packing 5.Described system thereby very clean.
In this enable possition, for example the pressure of steam delivery fluid flows in the suction chamber 25, produced pressure drop introducing in the passage 33 and in the air induction passage 31 with the liquid of packing 5 internal communication, so that come liquid in the pumping packing 5 by Venturi-tube action, so the pressure in the suction chamber becomes and is lower than the pressure of the liquid top in the packing 5.Liquid thereby be injected in the combined shaft chamber 29 by means of restriction 26, and after homogenizing, pass injection catheter 48, the form with hot emulsion in this example is assigned with.Groove 35 and mouthfuls 36 can make packing 5 be full of air and the liquid packed in 5 has been evacuated, and the pressure of guaranteeing described package interior remains the pressure that is higher than described pressure drop, produces described pressure drop and is in order to ensure the continuity of pumping and prevent to subside to packing 5 inside.When delivery fluid when stopping to enter, suction chamber 25 is got back to the pressure higher slightly than the fluid pressure in the packing 5 heavily again, and this has guaranteed liquid is limited in the passage 33 and can not flow to the outside.The vacuum seldom that produces at packing 5 headrooms is enough to liquid is limited in the passage 33.
Pump in accordance with the present invention has been shown in Figure 14-16 has sent second embodiment of device, wherein, represented with identical label with the element components identical of describing in conjunction with previous drawings.
